Sometimes I go on challenge, and then wait 2 minutes until someone comes along, but in the minute of boredom, you know you decide to look up something on google or go wash dishes. Where i'm going to here, is wouldn't it be nice to get a sound or music change for when you begin a match, when opponent ends his turn.

On further developments I think it would be cool to have theme music (that can be bought for crystal like the sleeves or chosen for free) for each hero, or class/subclass.
